Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research from the University of British Columbia.
Roughly 3,600 years ago, the eruption of a semi-submerged volcano in the southern Aegean Sea devastated the island of Santorini, injecting ash, rocks and gas into the atmosphere and depositing kilometres of sediment in terraces on the seafloor.
The catastrophic eruption, and others like it, have traditionally been associated with abrupt climate shifts. But the minor climate impacts of more recent underwater volcanic eruptions, like that of Hunga Tonga-Hunga Ha’apai in 2022, have put that theory in doubt.
